The purpose of this study was to research the effects of the athletic experience and inter-stimulus intervals on the psychological refractory period. The subjects were 16 female athletes of a girls' middle school and 16 non-athletes who volunteered this experiment. The experimental apparatus was a multi-purpose reaction timer developed by Lee Kang-hun. The primary task(task 1) was two choice-reaction and the secondary task(task 2) was pushing a button. A 2×3{athletic experience×inter stimulus interval) two-way mixed design was used for this study. Dependent variables were RT1(the reaction time for task 1), RT2(the reaction time for task 2) and inter-reaction interval. As a result of 2-way ANOVA with repeated measure and contrast test for measurement, we gained the following conclusions. 1. RT1 has no difference between the experience of athlete and inter-stimulus intervals. 2. RT2 was shorter in athletes than in non-athletes. As the inter-stimulus intervals got longer, RT2 got shorter. 3. CRT2 was shorter in athletes than in non-athletes. 4. IRI was no difference between athletes and non-athletes, but increased as the inter-stimulus intervals got longer.

Facing competitive and complicated business environment, companies are developing new and diverse organization forms to overcome risk and to maximize performance. Virtual organization nowadays is considered as one of representative forms enhancing organizations performance. Virtual organization is created through a line of core competency among participating firms based on diverse cooperation structure. This study investigates the determinants of success of virtual organization based on the concept of trust since trust is one of important factors minimizing individual participant’s opportunistic behavior and uncertainty. The proposed research model was tested with 115 questionnaires. The result shows that the proposed hypotheses with respect to four determinants, uniqueness of knowledge, linking of knowledge, shared emotional understanding, and communication openness were partially supported. Implication and interpretation are discussed with cases and results.
